Description
Technical field
The utility model relates to a kind of equipment that detects bulk solid free flowability indexs such as grain.
Background technology
Free flowability is a kind of physical characteristics of bulk solid material, and it is meant that bulk solid is freely fallen by eminence, and scattering to come to all around forms the characteristic of a cone, promptly represents the wandering characteristic of this type material.The bulk solid of different material has different free flowabilities.
Grain also is one type of bulk solid, and it is deposited in a time-out after results, and different grain kinds also have different free flowability performances with the stage.For this physical characteristics carry out that quantitative index is confirmed, judgement and detection method thereof, have close association and meaning for social activities in production such as The Research of Relevant Technology, teaching, design, manufacturing, exploitation, application in the grain circulation process.
The specific targets of judgement free flowability are represented with repose angle.It specifically is defined as: bulk solid freely falls to the angle that formed cone inclined-plane line and horizontal bottom are constituted on the plane by the height point.Referring to Fig. 1.
This index is leaned on the protractor artificial visually examine to detect and is write down itself and the angle of baseplane formation after grain industry traditional detection method is grain to be scattered naturally form cone or inclined-plane.
For example its a kind of concrete detection method and process are: take out testing sample, remove impurity and unsound grain, with in its transparent cone container of packing into (being generally the glass triangle bottle); Charge weight is 2/3 of a container volume; Cover lid places circular conical surface on the surface level, slowly the rolling circle cone; When treating that grain no longer glides, grain plane that seed forms and horizontal plane angle in the xylometer.
The manual form of such manpower detects, and error according to the people and the time is bigger, especially differs less or (different like moisture, degree of ripeness is not equal) difficult difference of differentiating with a kind of material influence factor when inconsistent in the tested material characteristic; The accuracy of testing result and accuracy all are difficult to guarantee.The artificial error that detects is difficult to judge and eliminate especially.
Summary of the invention
The purpose of the utility model provides a kind of equipment that detects bulk solid free flowability index such as grain just to existing weak point in the above-mentioned prior art.
The purpose of the utility model can realize through following technique measures:
The equipment of bulk solid free flowability indexs such as the detection grain of the utility model comprises the detection warehouse; Be placed in the interim hopper that detects warehouse top fed mouth place through the partition door that is arranged on the charging aperture place; Be arranged on the discharge door that detects the warehouse bottom, on the bulkhead that detects warehouse, have a vertical strip transparent glass window that is provided with; Outside detecting the storehouse, be provided with optical ranging sensor with strip transparent glass window opposite position place, this optical ranging sensor is installed on the positioning supports guidepost that is vertically set on the pedestal through the upper and lower displacement drive unit; Said optical ranging sensor inserts data acquisition and electric control box the corresponding interface through transmission and control line.
The corresponding output end of data acquisition described in the utility model and electric control box is connected with data display screen, also can be connected with the USB standard interface that computer interconnection transmits data,
Partition door described in the utility model and discharge door all can be through electronic or manual mode CSs.Described upper and lower displacement drive unit can adopt that any one is realized in the known technology: like gear & rack structure or the rib-loop screw-rod structure that is driven by propulsion system.
